Cambridge Investment Research Minimum Investment (2026): What It Takes to Open an Account

Guides › Financial Advisor Fees

Updated September 18, 2026. Quick answer: $25,000 for Cambridge Managed Account Platform (CMAP) / Flexible Managed Account Platform. Cambridge Investment Research’s own Form ADV Part 2A brochure states this figure directly, though the firm can waive or reduce it at its own discretion. At that minimum, Cambridge Investment Research’s own published fee schedule works out to $562.50 a year.

The minimum, in the firm’s own words

“CIRA typically imposes a minimum investment amount of $25,000 to establish an account on the Cambridge Managed Account Platform or Flexible Managed Account Platform.”

On waivability: “However, the minimum investment amount may be waived under certain circumstances for specific registrations or if you are part of a household that has at least one CIRA account with a value of $25,000.”

Minimum investment and what it would cost

$25,000 at CIRA’s disclosed 2.25% ceiling: $25,000 x 2.25% = $562.50.

What else to know

Cambridge’s brochure also discloses a separate, lower $5,000 minimum for its distinct WealthPort Program, a different platform than the CMAP fee schedule shown here.

What a larger account would cost

The minimum is only the entry point. On a $500,000 account, Cambridge Investment Research’s own published fee schedule runs up to $11,250 a year (the published maximum, which the firm says is negotiable); see the full dollar breakdown from Cambridge Investment Research’s own fee disclosure across several account sizes.

Already a client and thinking about the minimum a different way, like whether you could get a better deal elsewhere? Read the general mechanics of switching financial advisors, or use a dated termination letter once you decide.

Methodology. This page was built September 18, 2026, quoting directly from Cambridge Investment Research’s own current Form ADV Part 2A / wrap-fee brochure, with the source linked above. The annual-fee-at-the-minimum figure applies that same brochure’s own published fee schedule to the disclosed minimum dollar amount; any distinction we could not independently confirm this session is named as an honest gap rather than presented as verified. Nothing here is personalized financial, tax, legal, or investment advice, and it is not a substitute for reading the firm’s own Form ADV Part 2A.
